Today more and more families have personal computers . People have wider range of choice to communicate with the outside world .   Right . With the establishment of Internet and a lot of web companies , people are getting more and more dependent on the web .   One of the common uses of PC is that people can buy goods through it without going out to the physical stores .   Can you tell me how it is done ?   If a customer is interested in some certain goods , he can ask the web company to have the specimen of the goods shown on the color screen , and then the customer can place an order online to the sales company . And then the goods you want will be delivered to your home . The service is perfect and the delivery is free of charge .   I see . So great .
